<a name="glib-Version-Information.description"></a><h2>Description</h2>
<p>GLib provides version information, primarily useful in configure
checks for builds that have a configure script. Applications will
not typically use the features described here.</p>
<p>The GLib headers annotate deprecated APIs in a way that produces
compiler warnings if these deprecated APIs are used. The warnings
can be turned off by defining the macro <a class="link" href="glib-Version-Information.html#GLIB-DISABLE-DEPRECATION-WARNINGS:CAPS" title="GLIB_DISABLE_DEPRECATION_WARNINGS"><code class="literal">GLIB_DISABLE_DEPRECATION_WARNINGS</code></a>
before including the glib.h header.</p>
<p>GLib also provides support for building applications against
defined subsets of deprecated or new GLib APIs. Define the macro
<a class="link" href="glib-Version-Information.html#GLIB-VERSION-MIN-REQUIRED:CAPS" title="GLIB_VERSION_MIN_REQUIRED"><code class="literal">GLIB_VERSION_MIN_REQUIRED</code></a> to specify up to what version of GLib
you want to receive warnings about deprecated APIs. Define the
macro <a class="link" href="glib-Version-Information.html#GLIB-VERSION-MAX-ALLOWED:CAPS" title="GLIB_VERSION_MAX_ALLOWED"><code class="literal">GLIB_VERSION_MAX_ALLOWED</code></a> to specify the newest version of
GLib whose API you want to use.</p>

a check that the library in use is compatible with
the version of GLib the application or module was compiled
against.</p>
<p>Compatibility is defined by two things: first the version
of the running library is newer than the version
<em class="parameter"><code>required_major.required_minor</code></em>
.<em class="parameter"><code>required_micro</code></em>
. Second
the running library must be binary compatible with the
version <em class="parameter"><code>required_major.required_minor</code></em>
.<em class="parameter"><code>required_micro</code></em>

(same major version.)</p>
